Lewis has been on the club's practice squad after being acquired from Detroit
in August and will make the start in place of injured rookie EJ Manuel.

"Thad gives us the best chance," said Marrone on Monday. "We're going to give
him an opportunity to see what he has."

Manuel was hurt during last Thursday's against Cleveland, suffering a sprained
right knee ligament that will not require surgery. Fellow rookie Jeff Tuel
struggled as Manuel's replacement in the 37-24 loss, completing just 8-of-20
passes for 80 yards with an interception.

Tuel was nearly the opening day starter for the Bills after Manuel underwent
minor knee surgery in August, but the first-round pick recovered quickly and
was under center Week 1 against New England.

Lewis, meanwhile, doesn't have much more experience than Tuel. He has played
one game in his four-year NFL career, starting the 2012 season finale for
Cleveland against Pittsburgh. He connected on 22-of-32 passes for 204 yards
with a touchdown and an interception in a 24-10 loss.

The 25-year-old Duke product entered the league as an undrafted free agent in
2010 and spent the season on the practice squad of the St. Louis Rams. He then
joined the Browns in 2011 and spent that season, as well as all but the final
game of 2012 on Cleveland's practice squad.
